Jon Skip most of the un-need information and look for an "10 foot Box" after you learn what is an Eight Foot Box and what can be with it. While you are looking stop at Uhaul to order an Trailer Hitch from them. It is the same Vendor Name as any other one that you may see and the Towing Data is also the same. No Hitch and you may not pull when you do find that Pup Up with an Queen Size bed and all. While you are there you can discuss The Tow Vehicle To Trailer Electrical Wiring and an Trailer Brake Controller. Both of these are going to be needed because they keep you out of Court and The Hospital.
